1 Claim. 1

This invention relates to an improved book rest and copy holder. In somerespects it is an improvement in the structure shown by the priorHancher Patent No. 2,192,574 of 1940, manufactured by the assignee ofthe present application. A line indicating device in this disclosure isa specifically new and useful device for use with copy holders generallybut particularly useful for a simple copy holder of the Hancher type.The structure as a whole is adapted for low cost manufacture and forconvenient handling by the user.

In the drawings:

Fig. 1 is a. perspective view of taken from the front;

Fig. 2 is a similar view taken from the back;

Fig. 3 shows construction detail of the line indicator; and

Fig. 4 is a sectional view showing the gear and handle mounting for theline indicator,

The main part of the holder, apart from the line indicating means, isgenerally like that of the said Hancher patent. These similar parts arethe main rest plate H, the outwardly extending bottom ledge l2, the beadI3 to hold the pair of U-shaped holding members l4 slidably mounted insaid bead so as to be independently adjustable longitudinally andlaterally, the easel support I6 hinged to the back, and the pair of armsl8 and I3 pivoted to the upper portion of the back of plate I I, theextension pieces 20 slidably mounted on said arms, and the spring clips2|, all for their known functions. The similarity of the main part, inthe named details and their function, is clear on comparison with saidHancher patent.

The difierence in such details relates to the manufacture. For examplein the new structure each leg ID is made of metal cut from the back onthree sides of a rectangle to form a tongue. The tongue is then bentdown in to the form of a leg 10 as shown. In a similar manner a tongueis cut out adjacent each upper corner of the back. Each tongue is bentover to form an eye 3 on the back. The single piece easel support orwire l6 has its ends bent to fit these two eyes 9 and form hinge pivotsat those corners. These detail changes result in a lower cost of makingthe Hancher kind of copy holder and improve its appearance.

The line indicator for the copy holder will now be described. In itspreferred form shown, it consists in a short bottom strip 30, slightlyoverlapping the underside of ledge 12 at one end, and. fastened there asby screws. At the other end of strip 30 rests an angle footing 3| bentout horizontally from vertical strip 32. A corthe structure respondingupper bend 33 provides for a threaded rod 34 to be mounted vertically.The upper end of this rod is conveniently fastened for support by ametal screw 33' passing through bend 33. The

lower end is conveniently supported by passing through footing 3i andstrip 33 and fastened with a nut all as indicated. The vertical strip 32is additionally supported in its position by strip 39 welded on the backof the strip 32. The other end of strip 39 is overlapped on the back Hand fastened there by metal screws. The threaded rod 34 is provided witha carrier made of a short cylinder 35 fitted to slide along or turn onthe rod. This cylinder has a long slot, see Fig. 3, by which a gear 46may engage the teeth of the rod. The cylinder is preferably made bybending sheet metal to just about fit around rod 32 like a looped strapl, for sliding movement of the loop, i.e. the cylinder 35. The ends ofthis strap form are brought together and welded. The slot is formed byforming a U-shaped end on the strap formation, as in Fig. 3. Then gear36 may extend through the slot, the legs 2 may be welded to theoverlying end, of the strap form. This end is extended as indicatedbeyond the legs 2. A bearing for the gear is made in the extended end ofthe strap I.

The gear 36 is preferably fastened to a hub on one side, see Fig. 4. Tothis hub is fastened a turning handle 31 for the gear. The hub has a pin38, extending through the gear and beyond the other side, with a head onsuch pin. By heading over the pin on its outer end, it provides meansfor holding parts together with a coil spring 43 as described below.There is as shown, a straight edge or member 40 fastened by a screw ontothe strap end. A convenient arrangement is indicated by the small strip4|, see Fig. 2, placed on the back end of member 40, into which thescrew is threaded. The other end of strip 4| has an opening throughwhich the pin 38 of the gear handle passes, see Fig. 4. The pin extendsfar enough out from strip 4| for a little coiled spring 43 to be mountedon it. Then the head 42 is made at the outer end of the pin. This headis pushed against the spring 43 to compress it when the head is put onto hold the compression of the spring. Of course the gear handle ispressed oppositely in this assembly. The result is a friction mountingfor the gear. This makes it hard enough for the gear to turn, so that itwill not turn except when the handle 31 is used consciously for thepurpose. Thus the straight edge or member 40 will rest at that elevationto which it is moved by turning the gear handle 31.

It will now be seen that the straight edge, used to underlie the line ofthe copy to which the eye wants to be directed, may be moved to positionby turning the gear handle. Furthermore the straight edge may be swung180 on or off the copy on back N. This swinging operation is providedfor by the cylinder 35 turning on the rod While it is held to: a desiredelevation'by engage-, ment of the gear-teeth with the thread, on the rod34. When the thread is given a small pitch as indicated, 180 turning ofthe straight edge;

will not change its elevation enough tomatter; any. This structure makesan eificientlow-cost line indicating device for theacopyholdeit The lineindicating devicec-mayrbe appliedrandf removed as a unit device to thecopyxholder':

Sometimes it is desired to have,.a ,lineindicator..

and sometimes not, as the Work at the typewriter varies. When one iswanted it is very easily atitached by the metal screws indicated inFig. 1. It goes on and off as aeunit.

It will be noted that the-devicemay, be used, as-a book rest, or as; acopy holder forlong sheets and with or without aline indicating and,easily adjustable straight edge; The combination isadapted for low costmanufacture, several; kinds of convenient use, and,consideredasawholeisquite simple in appearance-aswellasspecifically new and useful.
